单选题Sally Kemmerer has, so far, escaped Northern California's rolling blackouts. But up on the roof for her Oakland home, workers are tapping into, perhaps, the most reliable power source, the sun. It could mean no more worries about blackouts or power rates. Sally Kemmerer, homeowner says, "I hope that we'll be able to zero out, you know, our electric bill. I mean that's definitely our goal." Turning the sun's rays into electricity is, of course, nothing new. But California's power crisis has cast a new light on the technology. Gary Gerber, a solar power contractor, says, "I might have been getting, say three phone calls a week a couple of months age. I'm getting six a day now, it's completely crazy." Alternative energy is even more attractive, thanks to a state rebate program. So far this month, California's energy commission has received 200 project applications. That is more than the number of applications all last year. Putting in a solar roof is still a relatively expensive proposition. This project cost around 45000 dollars. Even taking into account the state subsidy of 12000 dollars, that leaves a net cost to the homeowner of around 33000 dollars. Sally says, "We were happy to find out that, eventually, the system should pay for itself, you know 20-years, maybe." Aaron Wellendorf has had a p-v (or photovoltaic generator) for more than a year. Like most solar systems, his is not off the grid completely the utility still kicks in at night, or when there's no sun. But when there is bright light, things change. Wellendorf says, "I'm turning my meter backward with extra power that I'm generating." Backward? That's right! Wellendorf's meter tracks how much power goes back into the utility grid. Last year all the paid for electricity was a service charge. That charge was around five dollars a month. In fact, even after powering his super-efficient household appliances and his converted electric truck, Wellendorf generated a net surplus of more than 2000-kilowatt hours. Unfortunately, state law doesn't require the utility to pay him for that. Wellendorf says, "I don't get it in money, I just get the satisfaction of helping out the power grid." And, he gets the satisfaction of being energy self-sufficient.

单选题Every second in the United States alone, more then 250 animals are slaughtered for food, adding up to more than 8 billion animals each year. Reducing the amount of meat in one's diet is nutritionally, environmentally, and ethically beneficial. People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-eaters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide enough nutrients, especially protein end iron. Actually, according to A Teen's Guide to Going Vegetarian, by Judy Krizmanic, protein is found in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988 study found that some of the highest pesticide residues appear in meat and eggs. Diets including more fruits and vegetables will only make people healthier. Some skeptics believe that there will be a shortage of food if animals are not eaten. In fact, the opposite is true. More than 80% of the com and 95% of the oats grown in the U.S. are fed to livestock. The world's cattle alone consume enough food to equal the caloric needs of 8.7 billion people, more than the entire human population. One half of the water used in the Unites States also goes to livestock; 250 gallons of water produces only 11b. (=pound) of beef. If people eat less meat and more plants, the amount of available food will increase. Many people become vegetarians because they feel that eating animals is unethical. 90% of these animals are raised in confinement. Chickens and other birds have only about half a square foot of space each, and since they are raised so close together, a hot blade is used to cut off their beaks to prevent them from pecking each other to death. Likewise, pigs that are repressed will bite each other's tails, so both their teeth and tails are removed as soon as they are born. Eating animals is hazardous in numerous ways. Even a slight reduction in meat intake is better than nothing at all. Consuming less meat is beneficial to the health of animals, the health of people, and the health of the world.

单选题It has been challenging for most twentieth-century American policy-makers to recapture the memory of the early United States, Constitution and all, as a revolutionary force—to ascertain, in other words, the original motives of our founding fathers. The argument that the war was a revolution is essentially universal among the progressives like Turner, Becket, and Jameson, who argue that the war was fought for, or at least caused, greater democracy in the colonies, and generally agree that the war was a true revolution, not simply a rejection of British tyranny. Though this may be true—wars do tend to terminate Old Orders and ancient regimes — it is hardly a singular observation regarding the American Revolution. A more salient hypothesis is that the fight for greater democracy spawned not so much from a desire for change as an affirmation of the existing order. Those gaining votes and other social privileges only wished to profit from the existing system—these were no sans culottes beheading kings and aristocrats as the Frenchmen did in their frenzied Terror and Englishmen who desired home governance, at first seeking to preserve local autonomy and loyalty to the King, not to Parliament. It was only after the initial conflict that the revolutionaries slipped into the position of demanding sovereignty. Classwise, those ruling in 1770 also held power in 1790, while the Parliament, a bicameral legislature, was replaced by the Congress, another bicameral legislature and the King supplanted by a President, who could very easily have maintained his position for life. This nearly created a tradition that the head-of-state-for-life would be chosen without the benefit of heredity, a disastrous case suffered by twentieth-century Ugandans under Idi Amin. Furthermore, only propertied white males had suffrage, both before and after the war, and the end of slavery was not exactly accelerated by the war, though there were a few relatively minor gains for blacks. Meanwhile, the economic system was not altered, nor was the class structure, except to forbid a nobility that in any case had only a nominal existence in the colonies before the war. What the colonists sought was control to which they had already been accustomed. Parliament was not in the colonists "chain of command" in 1700, and for the House of Commons to attempt to place itself there was seen as a loss to the colonists. Alteration was what they resisted, not what the sought;they largely felt that they were resisting an invasion of their political birthright, not that they were breaking bold new political ground, and therefore, it would be very convincing to argue that the war was fought as a reactionary response, not as a radical one.
